Powers:Similar powers to Green Lantern of Earth-2 (Alan Scott), as he holds a piece of the same rock from which the lantern was formed.

Bio:Centuries ago, Chang saw a fiery green rock fall from the sky. He fashioned the rock into a green lantern - the same lantern that gave Alan Scott his powers. However, Chang kept a piece of the rock (referred to as "The Power-Stone") and it kept him alive for centuries although he was unable to use its full powers. Finally, his evil will conquered it when Alan Scott began using his ring for evil purposes at the hands of the Psycho Pirate. The "Power-Stone" became the "Dragon-Stone" and the stone began to obey Chang's commands.
